M.; Budochkina, S. A.AbstractUsing methods of nonlinear functional analysis, we define the structure of an evolution operator equation of second order that can be formulated in direct variational terms.SubjectsVARIATIONAL principles; NUMERICAL solutions to operator equations; NONLINEAR functional analysis; NUMERICAL solutions to Voterra equations; OPERATOR spaces; BILINEAR formsPublicationMathematical Notes, 2006, Vol 80, Issue 1/2, p83ISSN0001-4346Publication typeArticleDOI10.1007/s11006-006-0111-x
